Rheumatoid polyneurop w rheumatoid arthritis of unsp ank/ft

This code signifies nerve damage (polyneuropathy) affecting multiple peripheral nerves, specifically caused by or associated with rheumatoid arthritis. The rheumatoid arthritis itself is located in an unspecified ankle and/or foot. This represents a systemic autoimmune condition with neurological complications.

Use this code when documentation clearly links a patient's polyneuropathy to their rheumatoid arthritis affecting the ankle and/or foot. This diagnosis is appropriate when the physician explicitly states "rheumatoid polyneuropathy" or similar language, and specifies the involvement of the ankle/foot.

• Ensure the documentation explicitly states the polyneuropathy is due to or with rheumatoid arthritis.
• Verify the affected joint is an ankle or foot; if another joint is specified, a different M05.5- subcategory would be appropriate.
• This code inherently links the polyneuropathy to the rheumatoid arthritis; a separate code for the polyneuropathy (e.g., G63) is not typically needed unless further specificity is required.
